Title: A method of operating a vapour power plant
IPC: F01K7/22
Filed: 1964-07-01
Abstract: 1,074,947. Starting-up steam generators. COMBUSTION ENGINEERING Inc. July 1, 1964 [Aug. 8, 1963], No. 27244/64. Heading F4A. [Also in Division F1] In a power plant comprising a main vapour generator 20 feeding a multi-stage turbine 26, 38, 40 driving an electric generator, with reheating between at least some of the turbine stages, at peak outputs, an auxiliary vapour generator 84 is brought into operation to feed vapour to one of the later turbine stages. The auxiliary generator 84 may be that normally used in starting up the plant. The main generator has primary and secondary heaters 44, 50, which at starting can be isolated by a valve 52 so that steam from heater 44 passes to a flash tank 58 which, when operative, supplies steam to drive the feed pump turbine 14 and to operate deserator 10. Until tank 58 is fully operative, steam is supplied thereto by generator 84 which also supplies steam through pipe 78 to cool the section 50 and set the turbines rolling. After the start-up phase, valve 52 is opened so that steam from heater 44 flows through the secondary heater 50 and is fed to the highpressure turbine 26, from which it flows through a reheater 34 to the intermediate-pressure and low-pressure turbines 38, 40. At peak loads, auxiliary generator 84 is fired to deliver steam through valve 90 to a point upstream of the reheater 34. In a modification, Fig. 2 (not shown), the main generator delivers to a superpressure turbine stage (27) upstream of the remaining turbine stages (91), (39), (41), and the auxiliary generator delivers through line 88 either downwstream of the H.P. turbine (91) or immediately downstream of the superpressure turbine (27).

Title: Overload protective device for presses
IPC: B30B15/28
Filed: 1972-06-12
Abstract: 1372640 Deep drawing SCHULER GmbH 12 June 1972 [11 June 1971] 27264/72 Heading B3Q An overload protective device for a press comprises a fluid operated device, e.g. an hydraulic cushion or a fluid clutch, between the ram 1 and its drive, the fluid pressure in the device being varied during the operating stroke of the press. In one embodiment the cushion 2<SP>1</SP> is formed by a piston-cylinder assembly 2, 3 to between the ram 1 and its drive rod 5. The maximum pressure of the fluid permitted in the cylinder is controlled by a pressure relief valve 14 whose opening pressure is varied. The valve 14 is biased closed by constant gas pressure on the side 11 of a piston integral with the valve however the gas pressure on the side 25 of the piston is varied by movement of a piston 21 connected to a cam follower 22. The device and fluid system are mounted on the ram for movement therewith and the follower acts on a stationary cam 17. The pressure in the cushion may alternatively be controlled by electrically controlling a pressure relief valve or by using a series of switches operated in sequence as the ram moves or its drive rotates to control pressure release valves. The embodiment using a fluid clutch as the fluid operated device is not described in detail. The press may be a deep drawing press operated by a crank or eccentric or hydraulically.

Filed: 1927-10-14
Abstract: 284,965. Carrier Engineering Co., Ltd., and Groom, S. L. Oct. 14, 1927. Heating air.-A heater 7, disposed in the air supply duct 3 of a ventilation system, is controlled normally by a thermostat 15 arranged in the enclosure, and in addition a pair of thermostats 18, 19 are provided, one of which causes the supply of heat to be cut off when a predetermined maximum temperature is reached and the other operates to permit the passage of additional heat when a predetermined minimum temperature is reached. The heater consists of coils 7 to which steam is fed by a pipe 8 which is divided into two conduits 13, 14 controlled by valves 10, 11, 12. The valve 10 is normally open and is controlled by the thermostat 18, being adapted to be closed when the maximum temperature is reached. The normal thermostat 15 regulates the valve 11 in the conduit 13 according to fluctuations prevailing in the enclosure. The valve 12 is adapted to be opened by the thermostat 19 when the supply air is at a minimum temperature, and in this case the thermostat 15 may have operated to close the valve 11 due to the heat given off by people in the enclosure. The coil 7 may be divided into two parts 24, 25, Fig. 2, the coil 24 only being used under normal conditions, and the coil 25 coming into operation on the valve 12 being opened by the thermostat 19. The thermostats are adapted to operate the valves through a compressed air system and motors.

Abstract: 893,704. Hat fulling machines. BRUYERE, F. Aug. 10, 1959 [Oct. 8, 1958], No. 27333/59. Class 63 [Also in Group VIII] Relates to a fulling machine in which the felt hat blanks are fed between superposed rows of rollers, some or all of which are subjected to axial reciprocation. According to the invention the rollers are associated with levers controlling their reciprocation, and end of each lever 1 being subjected to the thrust of a cam 5 keyed to a spindle 6 driven by the power unit of the machine, while the other end engages the end 8 of the spindle c of the corresponding roller d, the lever pivoting at 2<SP>2</SP> about the end of a normally stationary carrier arm 2, the position of which is adjustable so as to modify the position of the pivot 2<SP>2</SP> in relation to the cam 5 and spindle end 8. Thus the ratio between the lever arms and hence the amplitude of reciprocation of the roller can be modified. In a modification the rollers of one row are mounted on a common cradle carried by slideways and the lever or levers engage the cradle for reciprocation of all the rollers carried thereby instead of individual reciprocation of the rollers. Other modifications are described.

In a prop assembly for mine galleries of the kind which forms the subject of Specification 719,170, a horizontal hydraulic jack 7, Fig. 1, is connected between the telescopic sole members 3 and 4, the piston 7d, Fig. 3, of the jack 7 being coupled by its piston rod 7c to the sole member 3 and the cylinder of the jack 7 being coupled to the sole member 4 by a lost motion linkage which consists of a slotted member 7a secured to the cylinder anda bar 8 secured to the sole member 4 and having a roller head 8a slidable in the slot 7b of the member 7a. The jack 7 is in hydraulic communication with the lower ends of double acting vertical jacks 5, 6 supporting the telescopic roof beam 1, 2. When the jack 5 is lowered by admitting pressure fluid through a conduit 5h at its upper end, fluid in the lower end is forced into the right hand end of the jack 7, which thereby extends, and when the lost motion provided by the slot 7b has been taken up, causes the sole member 4 jack 5 and roof girder 1 to be advanced. Similarly when the jack 6 is lowered by admitting pressure fluid through a conduit 6h at its upper end, the jack 7 is retracted by fluid expelled from the lower end of the jack 6, which when the lost motion has been taken up, causes the sole member 3, jack 6 and girder 2 to be advanced. The pressure fluid is supplied by a rotary distributer valve, Fig. 10 (not shown) to the conduits 5h, 5b, 6h, 6b in sequence, during which the whole prop assembly advances. Alternatively a sliding distributer may be used. Additional conduits, not shown, are provided for returning fluid displaced by the pistons 5a, 6a and 7d, to the pump reservoir.

Class 50 In a method of briquetting pit coal or lignite without the use of a separate binder, coal pulverised to a grain size not greater than 3 mm. is passed from a hopper 1 through a feed device 2 into a fluidised bed conveyer or rotary furnace 3, where furnace or other inert gases entering at G heat the coal in 3-5 minutes to a temperature 25-50‹C below the softening point. The heated small coal passes through a line 7 to a mixer 8, whilst the heating gases taking with them 20-40% of the coal, in the form of dust, pass through line 4 to a cyclone separator 5, the gases leaving at K. The coal dust is heated in the infra-red radiator 6, electric furnace or other rapid heating device, to 30-50‹C above the softening point in not more than 5 seconds, after which it is mixed with the remainder of the coal in mixer 8 and passed to a briquetting press 9. If inert gases, other than furnace gases, are used to heat the coal in furnace 3, the gases may be continuously circulated from the cyclone separator 5 back to the furnace 3, a gas heater being interposed between them.
